What causes the seasons?
Correct Answer
C. The earth is tilted so different parts get more direct sunlight during different parts of the year.
Explanation
The correct answer is that the earth is tilted so different parts get more direct sunlight during different parts of the year. This is the main cause of the seasons. As the earth orbits the sun, its axis is tilted at about 23.5 degrees. This tilt causes different parts of the earth to receive varying amounts of sunlight throughout the year. When a hemisphere is tilted towards the sun, it experiences summer because the sunlight is more direct and concentrated in that area. Conversely, when a hemisphere is tilted away from the sun, it experiences winter because the sunlight is spread out and less direct.
2.
Barometric Pressure is measured using a
Correct Answer
D. Barometer
Explanation
Barometric pressure is the measure of atmospheric pressure. A thermometer measures temperature, an anemometer measures wind speed, and a psychrometer measures humidity. Therefore, the correct instrument to measure barometric pressure is a barometer. A barometer is specifically designed to measure the weight or pressure of the atmosphere, providing an accurate reading of barometric pressure.
3.
Which of the following is not related to weather:
Correct Answer
C. Pollen count
Explanation
Pollen count is not related to weather because it refers to the measurement of pollen in the air, which is primarily influenced by the presence of plants and their reproductive cycles. While weather conditions such as wind can affect the dispersal of pollen, the actual count is not directly dependent on weather patterns. On the other hand, precipitation, wind speed and direction, and temperature are all key elements that are commonly associated with weather conditions.
4.
Which one of the following statements is FALSE:
Correct Answer
A. Weather results from the movement of air and changes in temperature, air pressure and humidity.
5.
Fog can not form without_____________air.
Correct Answer
C. Warm
Explanation
Fog can not form without warm air because fog is created when warm, moist air comes into contact with cool air. The warm air cools down rapidly, causing the moisture in the air to condense and form tiny water droplets or ice crystals, which we see as fog. If the air is already cold or freezing, there is not enough temperature difference to cause condensation and fog formation.
6.
A warm air mass slides over a cold air mass. This type of front can cause precipitation in the form of rain, sleet, or snow.
Correct Answer
B. Warm front
Explanation
When a warm air mass moves over a cold air mass, it creates a warm front. As the warm air rises over the colder air, it cools and condenses, forming clouds and precipitation. The type of precipitation that occurs can vary, depending on the temperature difference between the two air masses. It can range from rain, if the temperature difference is small, to sleet or snow if the temperature difference is larger. Therefore, a warm front is the correct answer because it describes the situation where a warm air mass slides over a cold air mass and causes precipitation in the form of rain, sleet, or snow.
7.
Neither cold air nor warm air advances or moves. Where the two fronts meet, temperatures do not change and gentle winds occur.
Correct Answer
C. Stationary front
Explanation
A stationary front occurs when neither cold air nor warm air advances or moves. This means that the temperatures do not change and gentle winds occur where the two fronts meet.
8.
A cold air mass and a warm air mass move toward each other. The warm air gets lifted over the top of the cold air and forms clouds. This often results in heavy rain or snowstorms.
Correct Answer
C. Cold front
Explanation
When a cold air mass and a warm air mass move towards each other, the warm air, being less dense, gets lifted over the top of the cold air. As the warm air rises, it cools and condenses, forming clouds. This lifting of warm air over cold air is characteristic of a cold front. Cold fronts often bring heavy rain or snowstorms as the lifted warm air cools and releases moisture, leading to precipitation. Therefore, the correct answer is cold front.
9.
Colder air forces warm air upward, which closes off warm air from Earth's surface.
Correct Answer
D. Occluded front
Explanation
When a cold front catches up to a warm front, it creates an occluded front. In this type of front, the colder air mass lifts the warm air mass off the ground, forcing it to rise. As the warm air rises, it becomes cut off from the Earth's surface, resulting in the closure of warm air from the surface. This process leads to the formation of an occluded front.
10.
__________is the condition of the air in a particular place at a specific time.
Correct Answer
C. Weather
Explanation
Weather refers to the condition of the air in a specific place at a particular time. It includes factors such as temperature, humidity, precipitation, wind speed, and atmospheric pressure. This term is commonly used to describe the daily or hourly variations in the atmosphere, including changes in temperature, cloud cover, and the occurrence of rain, snow, or storms. Weather conditions can vary greatly from one location to another and can have a significant impact on daily activities, agriculture, transportation, and overall human well-being.
